# Audits

[ether.fi](http://ether.fi) contracts are reviewed continuously, not once. Since February 2023, the protocol has published +30 reports from +10 independent security firms and audit programs, with new reviews commissioned for each major release. Every report is public in the [audit registry](https://github.com/etherfi-protocol/smart-contracts/tree/master/audits), named by date and firm.

Audits reduce risk. They do not remove it. The bounds that hold even if a review misses something are described in [Multisigs and controls](https://etherfi.gitbook.io/etherfi/security/multisigs-and-controls), and live exploits are addressed by active monitoring and response.

### Security audits

Independent firms that have reviewed [ether.fi](http://ether.fi) smart contracts:

* [Certora](https://www.certora.com/)
* [CertiK](https://www.certik.com/)
* [Decurity](https://www.decurity.io/)
* [Halborn](https://www.halborn.com/)
* [Nethermind](https://www.nethermind.io/smart-contract-audits)
* [Omniscia](https://omniscia.io/)
* [Paladin](https://paladinsec.co/)
* [Solidified](https://solidified.io/)
* [Zellic](https://www.zellic.io/)

Every report is public in the [audit registry](https://github.com/etherfi-protocol/smart-contracts/tree/master/audits), named by its date and firm.

### Bug bounty

[ether.fi](http://ether.fi) runs a public bug bounty on [Immunefi](https://immunefi.com/bug-bounty/etherfi), with rewards for critical findings in the protocol's smart contracts. The protocol also ran a competitive audit with [Hats Finance](https://github.com/hats-finance/ether-fi-0x36c3b77853dec9c4a237a692623293223d4b9bc4/blob/master/report.md) in December 2023, with the findings published in the registry.

### Verify independently

* [Audit registry](https://github.com/etherfi-protocol/smart-contracts/tree/master/audits): all +30 reports, by date and firm.
* [Deployed contracts](https://etherfi.gitbook.io/etherfi/contracts-and-integrations/deployed-contracts): the live addresses each audit covers.
* [Multisigs and controls](https://etherfi.gitbook.io/etherfi/security/multisigs-and-controls): who can change the contracts, and under what delay.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://etherfi.gitbook.io/etherfi/security/security-and-risks/audits.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
